Pfizer Ltd., based in Sandwich sponsored the Monk's Wall nature reserve which was opened by celebrity bird-watcher Bill Oddie in May 2000.

The site covers 69 acres and attracts many rare and migratory birds such as long-billed waders and the red rumped swallow. The reserve recreates wet grazing meadows which were common before land was drained for agriculture. Returning the site to its natural state has also allowed the establishment of many other indigenous plants and animals.

The local community benefits from the programme as a foot path around the reserve allows easy access for walkers and bird watchers.
